Abstract
- We demonstrate the facile and well-controlled design and fabrication of heterostructured and hierarchical 3D mesoporous NiSi<subscript> x</subscript>/NiCo<subscript>2</subscript>O<subscript>4</subscript> core/shell nanowire arrays on nickel foam through a facile chemical vapor deposition (CVD) technique combined with a simple but powerful chemical bath deposition (CBD) technique. The smart hybridization of NiCo<subscript>2</subscript>O<subscript>4</subscript> and NiSi<subscript> x</subscript> nanostructures results in an intriguing mesoporous hierarchical core/shell nanowire-array architecture. The nanowire arrays demonstrate enhanced electrochemical performance as binder- and conductive-agent-free electrodes for lithium ion batteries (LIBs) with excellent capacity retention and high rate capability on cycling. The electrodes can maintain a high reversible capacity of 1693 mA h g<superscript>−1</superscript> after 50 cycles at 200 mA g<superscript>−1</superscript>. Given the outstanding performance and simple, efficient, cost-effective fabrication, we believe that these 3D NiSi<subscript> x</subscript>/NiCo<subscript>2</subscript>O<subscript>4</subscript> core/shell heterostructured arrays have great potential application in high-performance LIBs.
